A police watchdog will ask its members to declare any involvement in campaigns for or against Occupy Central, amid questions over their impartiality in assessing complaints against officers arising from the mass sit-ins. At least seven members, including two lawmakers, of the 24-strong Independent Police Complaints Council have publicly made plain in recent weeks their stances on Occupy or the police's handling of the protests. Four sided with the police or were against civil disobedience, while three were supportive of the movement or critical of the police's performance. "The secretariat is drafting a mechanism for members to declare interests on this incident," a spokeswoman for the council said. "Whether a member holds any position in certain organisations may need to be declared."

Police have received more than 1,000 reports against officers at the protests that started a month ago. Among these, 27 were deemed "reportable complaints" and would be referred to the council's serious complaints committee. The seven members in question included Christine Fang Meng-sang, who offered to resign from the IPCC after signing a social workers' petition condemning the police's use of tear gas on protesters last month. Council chairman Larry Kwok Lam-kwong had persuaded her to stay on, she told Commercial Radio yesterday. However, she might recuse herself from Occupy cases. "The credibility and impartiality of the IPCC are highly important. Members who have either openly supported or opposed the movement should avoid vetting the related complaints." Fellow member Lawrence Ma Yan-kwok is a legal adviser to the anti-Occupy Alliance for Peace and Democracy. The council members targeted in the complaints were pan-democratic lawmakers Kenneth Leung and Helena Wong Pik-wan, who attended the protests to support Occupy. Both Wong and Eugene Chan Kin-keung, who backed and opposed Occupy, respectively, said members who made political statements should not be barred from assessing the complaints.
